Daylight Saving Time Considerations

Some regions within a time zone do not observe DST. Arizona (MST) and Hawaii (HST) stay on standard time year-round, which can create unexpected offsets with neighboring states during summer months.

For the EDT to CDT conversion specifically: EDT (UTC-4) and CDT (UTC-5) both observe DST. When both zones transition on different dates, the offset temporarily shifts by one hour for a few weeks. Always verify during March–April and October–November.
